The brush is simple to replace and allows routine maintenance without tools, helping to keep the robot operating at close to factory performance for perimeter cleaning tasks.

Key specifications

• Compatibility: designed for Xiaomi Viomi S9 / S 9 series robot vacuums
• Function: side-edge sweeping brush to direct debris toward suction inlet
• Material: flexible bristles suitable for dust and light debris pickup
• Mounting: quick-fit replacement for the vacuum’s side brush hub

How to use

Turn off the robot vacuum and place it on a flat surface. Remove the worn side brush by pulling it off the mount according to the vacuum’s user instructions, then press the replacement brush onto the same hub until it clicks or seats firmly. After replacing, run a short cleaning cycle to verify correct rotation and clearance; ensure the brush spins freely without obstruction. Periodically remove hair and fibers from the bristles to sustain performance.

Usage recommendations

Replace side brushes when bristles become visibly worn, bent, or the robot’s edge cleaning performance declines. For typical household use, inspect the brush every 1–3 months and replace as needed. Avoid using damaged brushes, and keep mounting area free of accumulated debris to ensure proper attachment and rotation.
